IBERIAN OFFSHORE has successfully completed a substantial structural engineering design project involving the relocation of two STS container cranes which have been recently transported from Rotterdam to Vigo. The cranes had served the ECT Terminal of the Port of Rotterdam and will now work at the Termavi container terminal of the Port of Vigo, part of the Davila Group.
The overall transportation project was managed by Altius and the cranes were transported by the MV Happy Sky, a heavy lift carrier supplied by BigLift. The IBERIAN OFFSHORE scope of work included the design and engineering of all temporary reinforcement for the lifting and maritime transport operations. The scope also included the detailed design of the crane seafastening structure and four substantial lifting trunnions fitted to each the two cranes. In additional to the structural analysis, IBERIAN OFFSHORE prepared all of the associated design drawings for approximately 80 tonnes of temporary steelwork required for each crane.
The 800 tonne mass and large overall dimensions of these cranes, together with the complexity of the lifting operation, presented unique engineering design challenges for a project of this type. IBERIAN OFFSHORE successfully applied the talents and resources of its engineers to develop optimal reinforcing, seafastening and lifting arrangement solutions. Over a period of three months, this included detailed engineering design followed by on-site fabrication supervision, while at all times working closely with Altius and their appointed marine warranty surveyors to ensure the operation proceeded safely and without incident.
This interesting and unusual project has proven the ability and readiness of the IBERIAN OFFSHORE team to undertake bespoke projects which present challenging problems and to successfully develop design solutions that meet client requirements.
